Al's Gritty Mix and existing plants...
As I was searching the net for recommendations in terms of potting soil for patio and indoor plants, I discovered on this forum Al's Gritty Mix.
Since I have a few container plants on my patio and indoors that need repotting, I decided to give it a try. I think that I have manage to find all the required ingredients. However, there is still a question for which I don't seem to be able to find an answer: what should I do with the soil in which my container plants are currently growing in? Should I remove most or all of it and simply replace it with Al's Gritty Mix?
What do you recommend?
Thanks for your help
